A user interface device (1) for a surgical simulation system (2), comprising a rigid shaft (21) pivotably supported by a frame (11), and movable in the axial direction but fixed with respect to rotation around its longitudinal axis, and a handle (20) having a sensor body (22) rigidly attached to said rigid shaft (21), and a grip portion (24) rotatable around said longitudinal axis relative said sensor body (22). The handle (20) further comprises a rotator sleeve (23) rotatable around said longitudinal axis relative said sensor body (22) and said grip portion (24), a rotation sensor (40) adapted to detect rotation of said rotator sleeve (23) in relation to said sensor body (22), and a signal interface (45) mounted on said sensor body (22) and connected to receive a first detection signal from said rotation sensor (40). Through this design, all sensor elements and electronic circuitry can be provided in or adjacent to the sensor body, leading to an efficient design and manufacturing. |
